      Irreproducible Timestamps

      Please see my blog post describing why Irving & Holden's timestamping implementation is broken. According to Carlisle's method, there is no record in the Bitcoin blockchain proving the existence of the clinical trial protocol from this study.

      WARNING: Users should not rely on Irving & Holden's method for producing blockchain-verifiable timestamps. Doing so could expose them to invalid timestamps, accusations of fraud or misconduct, financial loss, and sabotage. As discussed in my blog post, there are several established solutions for Blockchain timestamping that have been reviewed by expert cryptographers. I strongly encourage users to rely on one of these methods and to disregard this study from Irving & Holden.

      Feel free to reference my blog post:

      Or the GitHub analysis behind it:

      I will update this comment if Irving & Holden provide cryptographic proof of their timestamp and the validity of their method. Until then, I strongly urge readers to avoid advertising or building on this study.
